The HMC774 devices are general purpose double-balanced mixers available in a chip (HMC774) and a leadless RoHS compliant SMT package (HMC774LC3B), both of which can be used as an upconverter or downconverter. The HMC774 operates between 7 GHz and 43 GHz, and the HMC774LC3B operates between 7 GHz and 34 GHz. These mixers require no external components or matching circuitry. The HMC774 devices provide excellent LO to RF and LO to IF suppression due to optimized balun structures. The HMC774 operates with LO drive levels greater than 13 dBm, and the HMC774LC3B operates with LO drive levels greater than 15 dBm. The HMC774 wideband mixer exhibits consistent conversion gain and compression across its bandwidth. The HMC774LC3B eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.
